4:1 Balun question

Question

With an OCF dipole, does it matter which leg, short or long, is connected to which side of the 4:1 balun, hot(coax center) or shield? How can you tell which is which, the balun is not marked. Thank you.

I don’t know. It’s a Radio Works balun and completely sealed. About 3” Dia and 4” tall. — John, Feb 24 '20 at 00:55
I saw your post and wonder what your experience has been with the OFCD as I have the same question about which wire goes where but seems it does not matter. Any more thoughts about this? Thanks Steve — Shortwavesurfer, Oct 25 '21 at 13:42

It doesn't matter. If you change the connection of the OCF dipole nothing will change from the current and voltage flow or distribution points of view.

Phase

The only difference will be the RF phase. A "balun" is a transformer that goes between balanced and unbalanced sources and sinks of energy.

Unless you are trying to use two dipoles as an array, the phase doesn't matter.
